Subsea Actuator

RSUB Series

Smart Technology

The RSUB series was developed to support shallow and deepwater subsea applications requiring higher torque rating applications.     This series is IP 67 rated and provide a torque up to 400Nm and have been tested for depths to 750m (2500ft).  The RSUB series incorporates a Diver and ROV Friendly Clamping System for ease of installation and removal at any depth.   The Actuator comes with available features such as wiggle, multiturn, failsafe, modulation, torque control and speed control.  All actuators are supplied with a manual override handle.  Actuators can be customized to meet your Topside and Subsea Controls System.  Successful projects using our actuators include the Wave Power Renewable Energy industry in Europe.
